Purpose: This study aimed to compare and analyze the changes after applying extracorporeal shock waves(ESWs) and pulsed ultrasound to the thoracolumbar fascia to determine an effective intervention method forincreasing the range of motion of the trunk and reducing the pressure threshold.
Methods: We selected 22 men and women who voluntarily consented after receiving a detailed explanationof the study. The participants were selected from students attending G University and had back pain or limitedtrunk mobility. They were randomly selected to receive extracorporeal shock wave therapy (ESWT group; n=11)and pulsed-ultrasound therapy (n=11). The interventions were conducted twice a week for 5 weeks, andtrunk-side bending, rotation, and pressure pain thresholds were measured before and after the intervention.
Results: When ESWs and pulsed ultrasound were applied to the thoracolumbar fascia, the pressure painthreshold and trunk mobility improved. With respect to changes in trunk mobility, only the range of motionfor trunk rotation (P<0.05) increased significantly in the ESWT group; however, both ranges of motion for trunkside bending and rotation (P<0.05) significantly increased in the pulsed-ultrasound group. With respect topressure pain threshold change, both groups showed a statistically significant increase in pressure painthreshold (P<0.05).Moreover, a statistically greater increase in pressure pain threshold (P<0.000) wasobserved in the pulsed-ultrasound group than in the ESWT group.
Conclusion: Clinically, pulsed ultrasound treatment is more effective for increasing the range of motion andpressure pain threshold during interventions for people with back pain and limited trunk mobility.
